Provided is an electric connector capable of preventing damage to a housing and deformation of a fixture, even in the event of miniaturization. This electric connector (10) has: a first housing (30) having a recess section (35) in a first surface; a first connector (20) having a first fixture (54) that is held by a first housing (30) and faces the first surface; a second housing (70) in which a recess section (76) mated with the recess section (35) is formed in a second surface corresponding to the first surface; and a second connector (60) mated with the first connector (20) and having a second fixture (94), which is electrically connected to the first fixture (54), is held by a second housing (70), and faces the second surface. After the first housing (30) and the second housing (70) are mated, the recess section (76) is disposed so that a side surface along a direction perpendicular to the first surface faces the first fixture (54) or the second fixture (94), and the first housing (30) is formed continuous with the first surface and has a protrusion section positioned closer to the fitting side than the first fixture (54).
